1. Field of the Invention
The present invention relates to transfer lift devices and more particularly pertains to a new portable patient transfer assist system or improving the mobility and independence of persons with limited range of movement concerns.
2. Description of the Prior Art
The use of transfer lift devices is known in the prior art. U.S. Pat. No. 4,573,736 describes a device for assisting a patient to stand. Another type of transfer lift devices is U.S. Pat. No. 3,473,174 having an apparatus to assist a patient on and off a toilet.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a system that is superior in improving the mobility of patients by providing an easily transportable and easily operated transfer assist system
The present invention meets the needs presented above by providing a compact transportable device having a pneumatic lift for aiding in transitioning between sitting and standing.
Another object of the present invention is to provide a new portable patient transfer assist system that can be easily taken with the user to make facilities in locations being visited fully accessible.
Still another object of the present invention is to provide a new portable patient transfer assist system that reduces the likelihood of injury in transitioning between standing and sitting positions.
To this end, the present invention generally comprises a base assembly is designed for resting upon a horizontal support surface, a lift assembly operationally coupled to the base assembly having a stored position and an extended position and being fully adjustable between the stored and the extended positions, a seat assembly operationally coupled to a top end of the lift assembly designed for being sat upon by the user.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The invention will be better understood and objects other. than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The lift assembly 30 preferably is operationally coupled to the base assembly 20. The lift assembly 30 has a stored position and an extended position. The lift assembly 30 is fully adjustable between the stored and the extended positions.
The seat assembly 40 is preferably operationally coupled to a top end 36 of the lift assembly 30. The seat assembly 40 further comprises a main member 42, which is operationally couplable to the top end 36 of the lift assembly 30. The main member 42 is positioned horizontally. The main member 42 includes a right side and a left side. The main member 42 is designed for being sat upon by the user. The seat assembly 40 further comprises a pair of handle members 44. Each one of the handle members 44 is operationally coupled to and associated one of the right and left sides of the main member 42. The handle members 44 provide a gripping point for the user to enhance the users stability.
In an embodiment each one of the pair of handle members 44 is pivotally coupled to the main member 42. Each one of the pair of handle members 44 has an extended position defined by a first rail 45 of the handle member 45 being positioned above the main member 42. The extended position facilitates the user remaining on the main member 42 during operation of the lift assembly 30. The handle members 44 may be locked into the extended position to provide additional support for the user when transitioning positions or from one seat to another. Each one of the pair of handle members 44 has a retracted position defined by the first rail 45 of the handle member 44 being positioned below the main member 42. The retracted position facilitating the user transferring onto and off of the main member 42.
The control assembly 50 is operationally coupled to the lift assembly 30. The control assembly 50 facilitates adjustment of the lift assembly 30 between the stored positions and the extended position.
The lift assembly 30 further comprises an outer housing 32 and a ram member 35. The outer housing 32 includes an upper end 33 and a lower end 34. The lower end 34 of the outer housing member 32 is operationally couplable to the base assembly 20. The outer housing member 32 is substantially hollow. The ram member 35 is positionable within the outer housing 32 and is extendable from the upper end 33 of the outer housing 32. The ram member 35 is slideably adjustable within the outer housing 32. The ram member 35 has a stored position and an extended position. The ram member 35 is fully adjustable between the stored and the extended positions. The ram member 35 includes a top end 36, which is operationally couplable to the main member 42.
In a preferred embodiment the ram member 35 is a pneumatic ram.
In a further embodiment the control assembly 50 is positioned within the base assembly 20. The control assembly 50 is actuated by a foot of the user.
In another embodiment the control assembly 50 is coupled to the main member 42, and the control assembly 50 is actuated by a hand of the user.
In a further embodiment the system 10 includes an overall width of 12 inches to facilitate positioning in tight locations.
While the present invention is lightweight and easily transportable in its fully assembled form, the invention may be disassembled into its major constituent components to further aid in its portability.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
